摘要 :
Disclosed are a method and device for controlling set-up of a user side bearer, aiming to solve the problem of an unnecessary signaling overhead caused by the fact that a UE initiates a TAU process after an SGW deletes cached downlink data of the UE when a timer has timed out, and an MME still initiates a set-up process of a user side between the UE and a base station. The method comprises: in a tracking area updating (TAU) process, a mobility management entity (MME) determining that a serving gateway (SGW) needs to send cached downlink data to a terminal UE; and the MME initiating a set-up process of an air interface user side bearer of the UE.
